VALVE FOR OIL-CANS.

SPECIFICATION forming part of Letters Patent No. 635,658, dated October24, 1899.

Application filed January 18, 1899. Serial No. 702,497. (No model.)

To aZZ whom it may concern.-

\ Be it known that we, HADLEY O. CLAPP and EMANUEL LAWSON, citizens ofthe United States of America, and residents of Brewer, Penobscot county,Maine, have invented certain new and useful Improvements in Valves forOil-Cans, of which the following is aspecification.

This invention relates to oil-cans, and has for its object to provide animproved valve of simple and cheap construction whereby the oil may beprevented from leaking out from the orifice of the can when said valveis closed and providing a free outflow of oil from the orifice of saidcan when said valve is opened.

In accordance with this invention the valve may consist of aslightly-tapering tube arranged in the side wall of the oil-can near theupper end thereof, and said tapering tube is provided with aperturesthrough the side walls thereof communicating with a nozzle ordischarge-pipe and with the interior of the oil-can. A tapering plug isarranged to work within said tube, having an aperture adapted toregister with said apertures in said tube when the oil in said oil-canmay be poured therefrom through said discharge-pipe, and means isprovided to move said aperture in said tapering plug out of registerwith said apertures in said tube to close said valve. An air-hole isprovided and arranged to admit air to said oil-can through said valve asthe oil passes out and to close as said valve is closed.

Figure 1 is a side elevation of an oil-can, showing the valve arrangedin the side Wall thereof open. Fig. 2 is a front elevation of anoil-can, showing the valve closed. Fig. 3 is a side elevation of theupper end of an oilcan with a part of the side wall thereof removed,showing the valve in section open; and Fig. 4 is a similar view to thatshown in Fig. 3, showing the valve closed.

The letter a denotes an oil-can of common construction, having ascrew-threaded cap a, through which said can may be filled. To preventthe oil from leaking from the orifice or discharge-pipe d of said can, avalve is provided consisting of a tube 5, closed at both ends, which maybe made slightly tapering, and said tube 7) is arranged in the side wallof said oil-can a near the upper end thereof. Said tube Z) may besoldered or otherwise secured in the side wall of said oil-can a,communicating with the interior thereof, as shown in Figs. 3 and 4.Apertures c c are formed in the side wall of said tube b, one of saidapertures, o, communicating with the interior of said oil-can a and theother opening into said discharge-pipe or nozzle d. A tapering plug 6 isprovided and adapted to closely fit and work within the interior of saidtapering tube I), having an aperture 6 adapted to register with saidapertures c 0, formed in said tube 12, when the oil in said oil-can maybe discharged through said nozzle d. Said tapering plug e is constructedand arranged to turn or revolve a part of a revolution to move saidaperture e, formed therein out of register with said apertures c 0,formed through the side walls of said tube 1), to close said valve, andsaid tube 1) has form ed therein a radial slot it, through which a stud92, secured to said tapering plug 6, projects, having a thumb-piece nfor opening and closing said valve, as shown in Figs. 1 and 2.

Said valve is provided with an air-hole m, constructed and arranged toadmit air to said oil-can a as the oil passes out, said air-hole 1%being formed by piercing said tube 6 and valve-plug c with a small holem, as shown in Fig. 3, said hole through said valve-plug 9 moving out ofregister with said hole be through said tube 5 and closing said hole mwhen said valve is closed, as shown in Fig. 4.

lVe do not wish to limit this invention to a tapering plug 6, adapted tobe turned or revolved radially to open or close the valve, as it isobvious from the construction herein disclosed that said valve may beoperated by raising or lowering said valve-plug e to move said aperture0, formed therein out of register with said apertures c a, formed insaid tube 1), and in such case said tube 2) and said valve-plug 6,adapted to work therein, will not be tapered, but will be of uniformdiameter. A

We claim- In an oil vessel, a tube or valve-casing set into an elongatedopening in the wall thereof so as to project beyond the outer and innersurface of said wall and provided at its lower end with anoutlet-opening for the escape of the contents of the vessel, and at itsupper end with an air-inlet opening and a slot,and a valve located insaid casing provided at its lower end With an aperture, and at its upperend with an aperture and a pin, the apertures in the valve adapted tosimultaneously register with the openings in the valve-casing, and thepin on the valve adapted to project through the slot in the valve-casingand provide means for operating the valve, substanm tially as described.

Signed by us, at Bangor, Maine, this 14th day of January, 1899.
